Application filed June 10, 1903. Serial No. 1392625.

To all whom it may concern:

Be it known that I, HARRY S. MCOOR MACK, a citizen of the United States, residing in New Rochelle, in the county of Westchester and State of New York, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification.

This invention relates to paper handling devices of typewriting machines, and particularly to means for gaging the sheet in the operation known as retail billing and charging and is an im rovement on the device disclosed in Patent o. 829,989 granted to me September 4:, 1906. In said patent a plate or table having gages is mounted on a rod to lie over the platen, the leading and side edges of the sheet being brought to register with the gages on said table, so that the first line of writing may fall at the desired point on the sheet.

t is one of the objects of the invention to improve said device with a view to avoiding the liability of the table being accidentally pushed to the right or left on its supporting rod, so that a new entry will fal out of columnar alinement with previous entries on the same sheet. For this purpose I provide the table-supporting rod with notches at letter-space intervals, amtmeans releasably engaging the notches to lock the table against endwisc displacement.

Another feature of the invention is to provide for a moderate range of adjustment of' the sheet-gaging table toward and away from the printing line on the platen. The plate is carried by means of a pair of bracle ets or other supporting devices upon a rod to which the brackets are attached, to permit adjustment of the plate along the platen. Said table is provided with slots through which extend screws to connect it to said brackets and pcrinitadjustnient of the table around the platen; the screws hcing conlincd in slollcil depressions formed in the table, so as not to project above the surface of the table. Said screws are preferably threaded into ears which are hinged or pivoted upon said brackets. to pcrmit the lower or front edge of the table to swing toward and away from the platen: said edge being preferably lipped to contact with the platen and guide thc paper up onto the table, and to avoid liability of the sheet accidentally passing hetwcen the table and the platen.

Other objects and advantages will herein after appear. In the accompanying drawings, Fi re :1 1s a plan of the platen frame of an nderwooc front strike typewriting machine provided with my improvements F ig..2 1s a. sectional end elevation of the same. Fig. 3 1s a perspective view ofone of the carrying brackets illustrating a releasable tooth or dog... thereon, to engage an of the notches constituting a rack for hol ing the plate against displacement along the platen.

Type barsl strike upon the front of a platen 2, which is mounted by an axle 3 in the ends 4 of a platen frame 5.

Lying directly over the platen is a plate or table 6 having at its front end a 11p 7 to contact with the platen, and at its rear end a ledge 8 serves as a gage for the front edges of the sheets. At the right hand end of the a platen.

The table is mounted upon a device consisting of a pair of brackets 10, 11, yield ingly splined upon a rod 12 extending along the platen and lined at its ends in the laten frame ends 4-; each bracket formed of sheet metal and bent hackwardly at 13 and upwardly at it, to form a yoke, whereby the platebracket is journaled upon the rod. in said yoke is seated a swing 15 which presses a key, in the form o a roller 16, into a groove 17 in the rod, whereby the plate 6 is held firmly in working position, as at Fig. 2, but may he turned upwardly and rcarwardly away from the platen, when desired.

The plate or table 43 is adjust-able toward and away from the printing line or print ing point on the platen. such adjustment being permitted by slots 18 formed in depressions 19 in the plate, screws 20 passing through the slots to engage cars '21 on which the plate is supported. The depressions are provided to cnahlc the headsot the screws to ho sunkcn cithcr flush with or below the top surface of thc plate i), so that they may not project and cngi-ige the edges of the paper and hamper the operator in adjurding the same.

The cars 21 are preferably hinged upon the forward ends of thc brackets 10. 11, each car hcnl back at 2". to receive a pivot sullicicnt friction or binding of the parts being provided durmg the manufacture of this joint .to prevent the plate 6 from turning too freely upon the hinge.

It will be understood that when the screws 20 are loosened and the plates slid upwardly or downwardly on the cars 21, and the screws tightened, the plate may be turned about the hinges 2 to bring its forward lipped edge 7 against the platen. The operator is thus not only enabled to position the sheet accurately with reference to prior written lines thereon, but is also enabled to set the sheet so that the first written line will fall thereon in any desired position. The device is thus adapted for use with bills or forms, having specially ruled or printed headings.

The table 6 with its gage 9 may be adjusted along the platen; and to prevent accidental displacement of the plate in this direction, which is sometimes liable to happen during the constant use to which the table is subjected, I form upon the rod 12 a series of notches :24 forming a rack, and upon the bracket 10 I provide a dog or tooth 25'to engage the rack, as at Figs. 1 and 3, so that such accidental displacement of the paper-adjusting plate (3 is prevented. The dog 25 is pivoted at 26 upon an car 27 of the bracket 10, and is formed with a fingerpiece 28, which is depressiblento swing the dog out of the rack, as at Fig. 2, ,thereby releasing the plate for adjustment along the rod or rack bar 12., The movement of the I key 28 is limited by a stop 29 formed on the dog. It will be seen that the dog is forked at its lower end to bestride thejrod 12, one member of. the fork being engageable with the rack notches 24-, and the other member 29 serving as a stop to engage the front side of a rod 12 and limiting the depression of the key. Any suitable spring as 30 may be provided to return the dog to normal position.

Having thus described my invention, I claim:
